Question

For some reason.... I'm getting a null pointer exception..... while adding elements to an arraylist. I'm not even sure how that can happen...

Answer 1

Here's the code snippet
```
public void hash(Scanner scan){
ArrayList resList = null;
ArrayList nameList = null;

String[] stringsForArray = getArray(scan);

for (String newElement : stringsForArray) {

if(isReserved(newElement)){

resList.add(newElement);
}

else{

nameList.add(newElement);
}
}
hashReserved(resList,scan);
hashName(nameList, scan);

}

```

Answer 2

```
nameList.add(newElement); //here is where I'm getting the error.
```
